Most 18650 battery chargers handle one chemistry and two or four cells at a time. The LiitoKala Lii-S8 is built for people who need considerably more than that:
- 8 independent charging slots, each managed separately
- 2 dedicated ports for 9V rechargeable batteries, on either side of the display
- Automatic battery-type detection, with a manual current override when you want one
- Up to 2A fast charging on four of the eight slots
This guide covers what the Lii-S8 charges, how fast, how it compares with the smaller Lii-S6 and Lii-D4XL in RAM's lineup, and which of the three actually fits your workload.

What Is the LiitoKala Lii-S8?
- An 8-slot smart charger with two additional dedicated 9V ports — 10 charging positions in total.
- Each of the 8 main slots operates independently, so different chemistries and sizes can charge side by side at the same time.
- A microcomputer measures each cell's internal resistance and sets an appropriate charging current automatically.
- You can override that current manually with a long press on the CURRENT button.
- A single LCD shows the charging process; the NEXT and PREV buttons cycle through each slot to read voltage, capacity, percentage and detected battery type.
- An activation function can bring fully drained (0V) cells back to a chargeable state.
- Runs from a DC 12V / 4A input (48W). The box contains the charger, an AC wall adapter and a 12V car adapter.

- Ni-MH / Ni-Cd: A, AA, AAA, SC and C cells.
- Large-format cells such as 32700 fit the bays as well.
- 9V rechargeable Ni-MH blocks go into the two side ports, not the main bays.
Charging Currents and Speed
Charging speed on the Lii-S8 is not uniform across all slots, and it is worth understanding the pattern before you load it up:
- There are five current levels available: 0.30A, 0.50A, 0.70A, 1.00A and 2.00A.
- The 2A rate is available on four channels only — slots 1, 3, 6 and 8.
- All eight slots support 0.3A, 0.5A, 0.7A and 1A.
- Ni-MH and Ni-Cd charging is fixed at 500mA per slot and is not user-selectable.
- The two 9V ports charge at a fixed rate of approximately 85mA each.
- By default the charger picks the current itself based on the measured internal resistance of the cell — a long press on CURRENT lets you change it.

A practical note: the manufacturer's own guidance is to stay within each battery's recommended charging current rather than defaulting to the fastest setting available, and to keep the charger in a ventilated indoor spot while it works.
Safety and Protection Features
Charging several chemistries in one device raises the stakes on protection. The Lii-S8 includes:
- Automatic polarity detection — the cell charges whichever way round it goes in
- Over-charge protection
- Over-current and over-voltage protection
- Short-circuit protection
- Temperature control
- Soft start
- Damaged-cell detection — an abnormal battery or channel shows CH and Err on the display with a red channel indicator
- Automatic cut-off — the battery symbol stays full at 100% and the indicator turns green when charging finishes

Three things the table makes clear:
- Slot count and speed are the real dividing line. The Lii-S8 is the only one of the three that charges eight cells at once, and the only one with 2A available on four channels.
- 9V support is not exclusive to the Lii-S8. The Lii-D4XL also carries two 9V ports at the same approximate 85mA rate. If 9V charging is your only requirement, the cheapest unit in the lineup already covers it.
- The Lii-D4XL has one advantage the bigger units do not: a built-in AC power supply, so it plugs straight into the wall with no external 12V brick. It also takes C and D cells, which the Lii-S6 does not.

Who Should Buy Each Charger?
- Choose the Lii-S8 if you regularly cycle six or more cells at once — workshops, repair benches, drone and RC users with multiple packs — or if you want the fastest turnaround, since it is the only unit here with four 2A channels and a 48W supply.
- Choose the Lii-S6 if you need mid-range capacity at a lower price and do not need 9V charging or C and D cells. It still gives you 2A on three slots.
- Choose the Lii-D4XL if your volume is lower — a handful of cells for flashlights and small electronics — but you want AC-direct convenience, 9V support, or the ability to charge C and D cells. The trade-off is a 1A ceiling, so each cell takes longer.
Which Batteries to Use With the Lii-S8
A charger is only as good as the cells you put in it. RAM stocks a 3.7V 18650 lithium rechargeable cell that pairs directly with this charger:

Two habits worth adopting whatever cells you use:
- Match the charging current to the cell, not to the charger. A 2A setting is useful for a healthy high-capacity cell and unnecessary stress for a small 14500 or an older, tired one.
- Take batteries out once the display reads 100% and the indicator turns green, and unplug the charger. Leaving cells sitting in a powered charger indefinitely is the single easiest habit to fix.
Buying the Lii-S8 in Egypt
- All three chargers — Lii-S8, Lii-S6 and Lii-D4XL — are stocked by RAM Electronics and priced in Egyptian pounds.
- The Lii-D4XL runs directly from AC 110–240V, which matches Egyptian mains without an adapter. The Lii-S8 and Lii-S6 use their supplied 12V DC power adapters.
- Prices listed in this guide were correct in August 2026. Check the product page for the current price before ordering.
- You can collect from the RAM store or order for delivery — the product page shows the current options at checkout.
Frequently Asked Questions
Can the Lii-S8 charge different battery types at the same time?
- Yes. Each of the 8 main slots operates independently, so Li-ion, LiFePO4 and Ni-MH / Ni-Cd cells can charge simultaneously in different slots.
Which slots support 2A fast charging?
- Slots 1, 3, 6 and 8. The other four slots run at 1A or below.
Does this charger work with 9V rechargeable batteries?
- Yes — two dedicated 9V Ni-MH ports sit on either side of the display, each charging at approximately 85mA.
- Worth knowing: the smaller Lii-D4XL also has two 9V ports at the same rate. The Lii-S6 is not listed by the manufacturer as supporting 9V.
What is the difference between the Lii-S8 and the Lii-S6?
- Slots: 8 versus 6.
- Fast charging: 2A on four channels versus three.
- Power supply: 48W versus 36W.
- 9V: the Lii-S8 has two dedicated ports; the Lii-S6 does not list 9V support.
- Shared ground: both cover the same Li-ion, IMR, LiFePO4 and Ni-MH / Ni-Cd chemistries in the main slots.
Do I need to set the charging current manually?
- No. The charger measures each cell's internal resistance and selects a current on its own. A long press on the CURRENT button lets you override it if you prefer a specific rate.
Can it recover a battery that has drained completely?
- The Lii-S8 has a 0V activation function that can bring a fully drained cell back to a chargeable state. It is not a guarantee — a cell that has been flat for a long time may be past saving.
What comes in the box?
- The charger unit, an AC wall power adapter, and a 12V car adapter for charging on the move.
