Leave the lights on and the MB-14L still gets you home. A sealed reserve cell of 2.2 Ah sits apart from the main pack. Press the button on the case, wait ten seconds, turn the key.
IBMS
Protected on every cycle.
The integrated battery management system monitors voltage, current and cell temperature in real time. It cuts over-charge from a faulty regulator, prevents deep discharge from a parasitic drain, and stops thermal faults before they reach the cells.
Up to 70% lighter
2.3 kg on the scale.
The MB-14L weighs 2.3 kg (5.1 lb). MegaLiFe rates its LiFePO4 packs at up to 70% lighter than the lead-acid batteries they replace.
Drop-in fit
Factory tray. Factory hold-down.
Case dimensions are 150 × 87 × 105 mm with left polarity, matching the YTX14L-BS footprint. No relocation kit, no adapter plates.

Questions
Before you buy.
Is a lithium starting battery safe in my car?
Yes. MegaLiFe uses LiFePO4 (lithium iron phosphate), the most thermally stable lithium chemistry. Each pack is sealed, shock- and waterproof, and protected by an integrated battery management system that guards against over-charge, over-discharge and overheating.
Do I need a special charger?
Your vehicle's alternator charges a MegaLiFe normally. For bench charging use a lithium-compatible charger. We recommend our ML-BC14 series, sized 2A for motorcycles, 6A for small packs and 10A for vehicle batteries.
What happens if I leave the lights on?
Press the emergency start button on the case. A sealed reserve cell provides one full crank so you can drive home and recharge. It is a feature every MegaLiFe carries as standard.
Will it fit my vehicle without modification?
MegaLiFe cases are built to BCI group and JIS dimensions, so they drop into the factory tray with the factory hold-down. Check the group size on your current battery and match it on the product page.
